Pamela Anderson has been confirmed as a surprise housemate for tomorrow night's launch of regular Big Brother.

After crowning Paddy Doherty champion of Celebrity Big Brother, host Brian Dowling made the shock announcement that the Baywatch star will join 14 brand new housemates when the show launches on Friday.

Anderson was called to the Diary Room shortly after Doherty's interview, where she told Big Brother: "It's fun to be here."

She added: "I'm going to give them the ride of their lives, and leave a skidmark on every one of them."

Big Brother said that her appearance will be their "little secret", to which she replied: "Shhh!"

It is currently unclear whether Anderson will be a fully-fledged housemate or if her appearance will only be temporary.
